Beneath the surface lies an industrial realm waiting to be conquered, and your journey begins with a simple pickaxe. Extract ore, transport it to your base, and make a choice: sell it as is or transform it into raw materials and valuable goods. Seek out new veins of ore, set mine carts in motion, erect workshops and factories, delve into research, and forge a seamless production network.
Purchasing upgrades is just the start. Identify production bottlenecks, select lucrative recipes, prepare for special contracts, and determine where your scarce resources will have the greatest impact. When you're ready to expand, restructure your company, retain your advantages, and accelerate into a deeper production cycle.
Your enterprise continues to thrive even when you're away. Return to find stockpiled resources, adjust your production strategy, and witness your small mine evolve into a sprawling underground empire.
How to play
Start your journey in the copper mine by tapping «Mine manually». Fill the bunker, transport the ore to your base, and sell your initial batch. Use the earned hexes to invest in research and equipment.
Ensure each link in the chain operates smoothly: drills need to work, mine carts must deliver, and workshops and factories require a constant supply of resources. If a facility malfunctions, tap its status to identify and rectify the issue. Select recipes, preserve materials for research and large-scale projects, or distribute them through lucrative contracts.
Unlock new mines, automate the complex, and restructure your company to receive permanent bonuses for future cycles. Your progress is saved automatically, and part of your production continues even when you're not around.
